介绍了一种透射折射自适应光学系统，该系统采用可变形透明光流波前调制器和无传感器波前误差估计算法。波前调制器由填充有光学液体的腔体组成，该腔体由可变形的弹性聚合物膜密封。膜的变形是通过静电驱动使用25个透明的铟锡氧化物电极埋在空腔中。由系统产生的二维相位分布的调制使用具有和不具有主动波前感测的开环控制来执行。对于后者，使用渐进模式分解算法来估计和校正由于光学系统和其他波前畸变源而引起的波前的点扩散函数（PSF）中的畸变。使用这种控制方法，我们实验证明高保真重建泽尼克模式的四阶，和盲目的（无传感器）PSF校正在宽视场显微镜。(C)2018美国光学学会
We introduce a transmissive refractive adaptive optics system featuring a deformable transparent optofluidic wavefront modulator and a sensorless wavefront error estimation algorithm. The wavefront modulator consists of a cavity filled with an optical liquid which is sealed by a deformable elastic polymer membrane. Deformation of the membrane is achieved through electrostatic actuation using 25 transparent indium tin oxide electrodes buried in the cavity. Modulation of the two-dimensional phase distribution generated by the system is performed using open loop control both with and without active wavefront sensing. For the latter, a progressive modal decomposition algorithm is used to estimate and correct distortion in the point-spread function (PSF) of the wavefront arising due to the optical system and other sources of wavefront distortion. Using this control method, we experimentally demonstrate high-fidelity recreation of Zernike modes up to the fourth order, and blind (sensorless) PSF correction in a wide-field microscope.
